Make Odor Checks Part of Property Inspections
Locate odor sources in lobbies, elevators, restrooms and waste rooms. Schedule zoned treatment and checks around footfall and opening hours.
Key Inspection Points
Restrooms & Exhaust Ventilation
Inspect drain water seals, traps, exhaust systems and cleaning blind spots. Distinguish drainage odors from cleaning issues.
Lobbies, Elevators & Corridors
Record stale and transferred odors during busy periods. Check HVAC, supply and exhaust air, and enclosed elevator cabins.
Pantries & Waste Rooms
Check waste removal, residues, standing water and odor transfer into neighboring passages. Record individual odor-retaining points.

Treatment & Verification
- Trace the Source
Engineering teams investigate drainage, exhaust and transfer routes first. Cleaning teams then clean and dry each zone.
- Plan the Treatment
Schedule work around opening hours and footfall. List high-use points, times and responsible staff in the handover checklist.
- Verify & Hand Over
Recheck the same route after the next busy period. Record remaining odor points and return them to the responsible team.
